The DT12-4 Power Supply / Control Unit can simultaneously power four classic Dedolight heads equipped with 20 W, 50 W, 100 W or mixed wattage lamps.

Its AC power input can be set for every AC power in the world from 100 – 255 VAC in 24 steps.

Each light output can be individually and independently switched in four distinct steps, each increasing color temperature and output:
1. Off
2. Low 3000 K
3. Medium 3200 K (10.7 V at lamp)
4. High 3400 K (12.2 V at lamp)

The DT12-4 also incorporates an input voltage indicator allowing the user to determine the correct input voltage setting at a glance and to precisely control the color temperature.
